Some demonstrative embodiments include apparatuses, systems andor methods of transmit power control for wireless communication. Each storage cell is formed between a top an bottom electrode. A display device is mounted to the body, and a user interface is communicatively coupled to the display device. The aggregate surface remaining after developing acts as a polishing surface. The color controller may be configured to modulate the light received at the light input. The method includes: determining at least two user equipments being paired in a virtual multiple input multiple output system; and in accordance with the orthogonality of the at least two user equipments, adjusting at least the power of one of the user equipments.
